Our invention relates to juice extractors and more'particularly to a device for extract ing the juices from oranges, lemons, (311.1118 and other like fruits, and has for itsprmcipal object to provide for the complete extraction of such juices with facility and ex-. treme rapidity.

A further object of our invention is to separate the seeds and pulp from the juice so as to obtain the juice in its purest quality when pouring the same from the receptacle.

Another important object of the invention is to provide a device inexpensive of manufacture in that the various parts may all be formed of metal stampings and the parts readily assembled and secured together.

A; still further object of the invention is to provide a fruit juice extractor having a rotatable fruit carrier upon which hand pressure is exerted as the fruit is forced over the reamer or juice extracting member.

Other and further objects of our invention will be apparent from the following specification taken in conjunction with the accompanying drawings, wherein- Figure 1 is'a perspective view of the preferred embodiment of our invention, illustrated in fruit-receiving position;

Fig. 2 is a detail perspective view of the pulp disintegrating e ement;

Fig. 3 is a perspective view of the device in closed position after the juice has been extracted;

Fig. 4 is a longitudinal vertical sectional view through the same; and 7 a Fig. 5 is a plan view of the juice retaining receptacle.

Referring more in detail to the drawings:

1 designates a juice receiving receptacle comprising a cup-shaped member formed of sheet metal and having a cylindrical wall 2, an integral fiat bottom 3, and. an open top 4 throughwhich is projectable a fruit engaging or impalingmember 5.

The impaling member is also constructed of sheet metal and comprises a cone-shaped cup having a rounded top 6 and an outwardly flaring side wall 7 terminating in a laterally projecting peripheral flange 8 of a diameter slightly smaller than the diameter of the juice receptacle so that the impaling member is readily receivable therein as will be hereinafter described.

FixedVt-o the curved top of the impaling member by rivets 9 is a cap 10 having an upstruck boss or shouldered portion 11 provided with an opening 12 for receiving an end 13 of a shaft 14 whichis riveted therein as at 15, the shaft being rotatably mounted in a yoke 16, which comprises a bar 17 having laterally projecting ears 18 and 19 provided with apertures 20 for receiving the shaft and providing a two point bearing therefor.

Riveted to the yoke 16 by the rivets 21 is an arm 22 which, co-acting with a complementary arm 23 projecting laterally from the wall of the receptacle 1, forms a handle for the device, the arm 23 being secured to an ear member 24 riveted to the juice receptacle and having a laterally projecting ear 25 for attaching the end of the arm by fasteningdevices 26. The arm 22 projects downwardly from the yoke toward the rim of the receptacle, as at 27, and then laterally thereof in substantially parallel alignment with the arm 23 so that the arms may provide means for pivotally attaching the fruit impaling member to the juice receptacle through a hinge element designated 28.

The hinge element 28 comprises a pair of yoke-shaped members 29 and 30 riveted to laterally'bent-ends 31 and 32 of the arms 23 and 22 respectively, each member having pairs of pro ecting ears 33 and 34 to receive a pintle 35 for hinging the members together and pivotally mounting the impaling member to the receptacle to permit the impaling member to be swung out of engagement with the receptacle for insertion of the fruit and then swung back to juice extracting position as the fruit is urged into engagement with the pulp engaging member 36.

Thg uice extractor 36 comprises a semielliptic wire form of substantially the shape of the vertical cross section of the fruit impaling member. The wire presents a blunt edge to engage the juice containing cells of 1 the fruit thus enabling the more efiective extraction of the juice therefrom. This'member has opposed laterally bent hook-shaped ends 37 and 38 for engaging the heads 39 and 40 of pins 41 and 42 that are secured to the bottom of the juice receptacle so that the wire form may be readily detached therefrom for cleaning purposes. The pins are provided. with shouldered extensions 43 which project through openings 44 in the receptacle and are riveted to-its under side to firmly secure the rivets in position for retaining the wire form 36.

In order to rotate the fruit retaining member 5, the shaft 14 is ppovided with a crank 45 threadedly secured to a reduced extension 46 of the shaft. Itwill thus be readily apparent that when the crank is screwed in position, the shaft is retained in the yoke but may be readily removed for cleaning purposes by unscrewing the crank and slipping the shaft from the yoke.

In order to insure positive rotation of the fruit, the member 5 is provided with instruck V-shaped tangs 47 that project inwardly of the member 5 and may project forwardly in the direction of rotation so that the fruit is impaled thereby and positively rotated with the impaling member 5. We prefer to provide the impaling member with two or more rows of tangs 48 and 49 to insure engagement with the various sized fruits such. as lemons, oranges and grapefruit,.with-- in the capacity of the cone during the juice extracting operation, but this is not essential.

The receptacle 1 is provided with two pouring spouts 50 diametrically opposite each other and on opposite sides of the handle. In operating the device constructed as described, the impaling member 5 is swung on the hinge member 28 to the position shown in Fig. 1. The fruit is then cut into two parts and one of the portions inserted into the impaling member with the tangs 47 piercing the skin of the fruit. The impaling member is then lowered into engagement with the wire form 36 and while the left hand grips together the arms 22 and 23 of the handle member, the crank 44 is manipulated with the right hand, to rotate the fruit over the wire form. As the pulp gives way by rotation over the juice extractor, the impaling member is gradually and progrwsively lowered until the arm 22 engages the rim of the receptac1e,fwhereupon all the fruit juice has been extractedand is ready to be removed for use. 7 I The operator continues to grip the handle members 22 and 23 together and by tipping the device sidewise, the juice is poured from the spout 50 of the container into a glass or the like, and as the j nice poursvout,the seeds and loose pulp are retained by the flange of the impaling member, since, as before stated, its fit is fairly close within the receptacle to allow only space for the juice to escape, after which the skin, pulp and seeds may be removed, or the juice from the other half of the fruit may then be extracted in like manner, leaving the seeds and pulp accumulate in the cup. The juice may be poured from either lip 50, or partly from one side and partly from the other.

Attention is particularly called to the fact that the juice extracting member is wider than the fruit so that the skin is stretched along its plane thereby and as the skin is rotated thereover, the skin moves-in an elongated curvilinear path about the form, as shown by the dotted lines in Fig. 5, and it s partly by this peculiar motion that the juice is so'efliciently and easily removed. It Wlll also be noted that the hooks on the juice extracting member are so positioned that the rotative movement of the fruit tends to keep them in engagement with the pins, and that the nnpaling tangs may likewise be positioned toward the direction of rotation so that the tangs easily pierce the skin as it is engaged and disengaged during its movement about the juice extractor.

From the foregoing it will be readily apparent that wehave provided a device that is well adapted-to the purpose for which it is intended and which will speedily and easil extract juices in a-clean and sanitary condition, free from seed, pulp or other obj ection al matter.
